Does it mean the overhead of SCI interrupt was not the root cause of this issue. --Luming

Just a precision,
synaptic driver is not like the other mouses. psmouse call a specific fonction for this touchpad that is in an other module.
The problem happens since 2.6, since psmouse and synaptic had been seperated....

Hi!

  

It sound like serious one, if SCI interrupt handler was blamed for
this issue.     --Luming
    

I investigated a bit, and interrupt latency alone is not enough to
break mouse. [Unfortunately, I do not have easy/sure way to reproduce
it.]

Is it possible that SCI interrupt handler accesses keyboard controller
(and breaks mouse?)
